Title: Improvements in or relating to data sensing apparatus
Inventor: GUIVER REGINALD RICHARD
IPC: G06K7/016
Filed: 1959-09-18
Abstract: 961,141. Sensing record cards. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Aug. 26, 1960 [Sept. 18, 1959], No. 31850/59. Heading G4M. In a record sensing apparatus the output signal derived from sensing a mark is delayed after the instant that the mark is sensed by an interval which varies according to the speed of operation of the apparatus, the delay being smaller for a higher speed. In the form of Figs. 1 and 2 sorting deflectors 9 are operated by magnets 14 at an instant which causes the leading edge of the card 1 to enter the correct channel. The perforations in the card are sensed by brushes 8. At slow-speed operation the signal must be delayed relative to the card movement to obtain correct sorting whereas at high-speed no delay is necessary. The signal from the brush 8 is picked off the contact roll 3 by brush 7 and applied to a differentiating circuit consisting of condenser 21 and either resistor 33 or 43 depend ing upon whether centrifugal switch contact R1a is open or closed. The signal derived from sensing a perforation is therefore a positive pulse followed, as the brush 8 is lifted from the contact roll 3, by a negative pulse. A gas tube 24 is fired by a negative pulse on lead 23 or a positive pulse on lead 31. When the speed is low the switch R1a is in the position shown so that the tube 24 is fired by the negative pulse passing through diode 22. The operation of magnets 14 is accordingly delayed until the end of the perforation is detected. As the speed increases the centrifugal switch operates to transfer the contacts R1a so that the signal is applied to the lead 31 and the magnets 14 operate when the beginning of the perforation is detected. A number of tubes 24 could be provided each with a delay circuit which are selected in turn by centrifugal switches so that the delay period is varied in a series of steps as the speed increases. The delay using only the period of sensing could be increased by lengthening the perforations or by increasing the length of the sensing brushes 8. Instead of using the period of contact through the holes of the record as the delay period cam contacts 35 may provide a short pulse within the hole-sensing time and the delay may be varied by a mechanical device similar to a conventional speed governor which controls an electrical delay circuit by varying a resistance. In the form of Fig. 4 data sensed from a tape 43 is passed to a printer 44 which takes time to operate. Photocells 55 sense the data holes and a photocell 56 detects the sprocket holes. The tape is driven by a pin wheel on shaft 51 which also drives a speed sensitive device 57. This controls a rheostat 58 to determine the delay period of a delay unit 59. The sprocket holes produce timing pulses in photocell 56, which timing pulses may be delayed by unit 59 and then used to gate out the signals appearing on the photocells 55. Alternatively the undelayed timing pulses may gate out the data signals which are then delayed by unit 59.

Title: Process for separating hydrocarbon materials
IPC: C10G7/00
Filed: 1974-07-19
Abstract: 1469866 Separating hydrocarbon mixtures and separating water from oils A JOHNSON & CO Inc 19 July 1974 [20 July 1973] 32116/74 Heading C5E A continuous process for separating at least one hydrocarbon fraction from a liquid mixture of hydrocarbons comprises introducing the mixture continuously into a flow path, a portion of which has an elongate cross-section in a direction transverse to the flow of the mixture, supplying heat to the mixture as it passes along the portion of the flow path to cause progressive volatilization of part of the mixture with a resultant substantial increase in the velocity of the mixture, discharging the mixture from the flow path and rapidly separating the released vapours of the hydrocarbon fraction from the concentrated liquid hydrocarbon material. A feed 13 of asphalt diluted with diesel fuel is heated at 16 and 21 and then in the plate heaters 25 and 26. The heaters 25 and 26 each comprise a series of closely spaced parallel plates (Fig. 2, not shown) which can be corrugated, the feed to be heated and separated is passed through a space formed between two of the plates and hot oil heating medium 48 is passed through another such space-a number of such plates can be arranged side by side to provide more than one channel for the feed and more than one channel for the heating medium. The release of the diesel fuel as vapour in heater 26 is assisted by stripping steam 47. The heated vapour-liquid mixture is passed through a short line 60 into a separator 62 in which liquid asphalt 66 and diesel fuel vapour 65, which is taken off through a rotating vane tuyere 70, are obtained. The process can also be used to separate a gas oil from a reduced Venezuelan asphalt crude oil, as an alternative to vacuum flashing, or to separate a mixture of used motor oil, lubricating grease and water.

Title: Rolling bearings
IPC: F16C23/08
Filed: 1973-07-06
Abstract: 1441802 Bearings SKF INDUSTRIAL TRADING & DEVELOPMENT CO BV 6 July 1973 [7 July 1972] 32290/73 Heading F2A In a roller bearing comprising radially outer and inner race rings, the pivot moment of the outer ring predominates over the pivot moment of the inner ring when the skew of the rollers is zero, thus ensuring that the skew angle of the rollers during operation will be positive so that the axial component of the friction forces generated between the rollers and the raceway surfaces oppose axial load on the bearing. This is achieved in one of the following ways: (a) making the contact surface of the outer ring rougher than the corresponding surface of the inner ring; (b) providing the outer ring with a groove in the middle of the raceway; (c) chamfering the edges of the inner ring raceway; (d) reducing the osculation between the rolling elements and the inner ring. The invention is particularly applicable to double row spherical roller bearings.

Title: Improvements in or relating to repeating systems and apparatus therefor, particularly for telephone systems
IPC: H04B3/20
Filed: 1922-11-29
Abstract: 206,715. Western Electric Co., Ltd., (Western Electric Co., Inc.). Nov. 29, 1922. Repeating and amplifying systems.-A two-way repeater has a pair of relays, one of which is operated by current in each direction to render the repeater effective in that direction, and a loaded circuit is provided to delay the incoming signals when this is done. In one form, incoming current over the line 10, Fig. 1, energizes a relay 45 which supplies anode potential to a thermionic valve 14 over a relay 39 and a chokecoil 41, and current to the input transformer 13 is delayed by the loaded circuit 12 comprising series inductances and shunt condensers. The amplified signals pass to the line 23 through a transformer 20. The relay 52 which is operated by incoming current over the line 23 is ineffective to bring the corresponding valve 30 into action, since the circuit supplying anode potential is broken by the energization of the relay 39. In a second form, the line 70, Fig. 2, is connected directly to the repeating element 71, and part of the output current passes to a rectifier 73 and energizes relays 74, 75, thereby unbalancing a bridge 76 to allow the signals to pass to the line 77, and opening the circuit of the rectifier 78 to prevent retroaction. The loaded delay circuit 81 is inserted between the repeating element 71 and the bridge 76. The relay 74 may alternatively remove a shunt across the outgoing line.
